Failure is essential. Trial and error is necessary. — © David Bergen
Failure is essential. Trial and error is necessary.
Error is not just acceptable, it is necessary for the continuation of life, provided it is not too great. A large error is a catastrophe, a small error is essential for enhancing existence. Without error, there is no movement. Death follows.
'Victory Lap,' even the title. It's the accumulation of trial and error; that's what I represent; trial and error.
As soon as error is corrected, it is important that the error be forgotten and only the successful attempts be remembered. Errors, mistakes, and humiliations are all necessary steps in the learning process. Once they have served their purpose, they should be forgotten. If we constantly dwell upon the errors, then the error or failure becomes the goal.
Sometimes, we find what we want by also finding out what you don't want. All of that is trial and error. Once you're in that pit, the trial and error is important. It's up to us; we've got to keep moving forward.
Be fearless and don't be afraid of failure. There is no better way to learn than through trial-and-error.
Fail your way forward. Recognize that Ready, fire, aim is superior to ready, aim, aim, aim. Straightforward trial and error produces better results than endless vacillating. If you're afraid to make decisions and act on them in the face of ambiguity and uncertainty, get a job. Failure's lessons are essential to success.
You don't learn from a situation where you do something well. You enjoy it and you give yourself credit, but you don't really learn from that. You learn from trial and error, trial and error, all the time.
Every failure is a step to success. Every detection of what is false directs us towards what is true: every trial exhausts some tempting form of error. Not only so; but scarcely any attempt is entirely a failure; scarcely any theory, the result of steady thought, is altogether false; no tempting form of Error is without some latent charm derived from Truth.
Only ... from personal experience [can a man] take the necessary measures without a preliminary process of trial and error.
Cities are an immense laboratory of trial and error, failure and success, in city building and city design.
You're always on duty because you're in a constant state of observation. That's one of the challenges of being a comedian. I think one of the other challenges is that, whether we like it or not, it's a profession that requires failure. It doesn't just encourage failure. It requires it because it's all trial and error. You need to know what doesn't work to know what works.
I had 11 years of managerial experience and four years of coaching before I managed a big-league team. To me, it was important, because I learned a lot through trial and error. And it's tough to have to go through trial and error when you're a big-league manager.
I never learned from a real trainer so it was trial and error. Mostly error.
science progresses by trial and error, and when it is forbidden to admit error there can be no progress.
Learn to fail with pride - and do so fast and cleanly. Maximise trial and error - by mastering the error part.
Every failure is a step to success. Every detection of what is false directs us towards what is true: every trial exhausts some tempting form of error.
